Fuel Rate

The Part No. 3376375, Fuel Measuring instrument, is

used during the performance check to measure fuel con-

sumption.

Install the fuel measuring device as follows:

• The fuel return hose from the engine to the fuel

measuring device (A).

• The fuel inlet hose to the fuel filter inlet (B).

• The return hose from the device (C) to the fuel tank.

• The fuel inlet hose to the device from the fuel tank

suction line (D).

NOTE: Adjust fuel rate to compensate for temperature vari-

ation if required.

Fuel Inlet Restriction

Measure the fuel inlet restriction. Install a vacuum gauge,

Part No. ST-434, between the fuel pump inlet and the

gear pump inlet.

NOTE: Do not measure fuel inlet restriction with the fuel

measuring device installed. This will not measure the inlet

restriction of the vehicle’s supply plumbing.

Hold the gauge at the same level as the gear pump.

NOTE: The gauge will not measure the correct vacuum if

the gauge is not held at the same level as the gear pump.

Engine Speed (RPM) With a Verified Tachom-

eter

Use digital optical tachometer, Part No. 3377462, to check

and verify engine speed.
